Abstract: Earth pressure cells which are buried in earth and rock-fill dams are usually caribrated in a tank filled with water. It has been pointed out, however, that observed values of earth pressure in the field are sometimes not in good agreement with those presumed by theoretical and empirical evaluations and that this is partly because calibration curves determined by use of water are not reflect stress-strain characteristics of fill materials. In the present investigations, some characteristics of earth pressure cells are examined experimentally in a soil bin by buring them in different positions, and theoretical considerations are given on them by use of the finite element methods. The effects of stress concentration, arching on the cell and side frictions on caribration curves of earth pressure cells are made clear by both experimental and analytical studies, and the best position of instrument in a soil bin is proposed to get the most appropriate calibration curve for field observations.
